BUILDING MATERIAL.

Application filed March 16, 1922. Serial No. 544,185.

To all 'whom t may concern.' A

Be it known that I, ROY Gr. BACHMAN, a

citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Building Material,

of which the following is a specification.

The present invention relates to building material. n

More particularly the present invention relates to material which may be fastened to the scantling of a house, either upon the interior or exterior of said'house, for providing weather-proofing means and means for supporting plaster, stucco, or other plastic wall covering material.

An object of the present invention is to provide building material which comprises weather-proofing material for houses, and also comprises means for holding plaster, stucco, or other lastic wall covering.

A further obyeot is to provide building material which will avoid the necessity for usin the lath which is commonly employed for olding plaster, stucco, or the like.

A further object is to provide building material having 'good heat and sound insulating qualities and which forms efficient means for holding plastic wall coverings.

A further object is to provide building material. which may be supplied 'in pieces convenient for handling, which may be readily shipped, and whleh requires only a ling of a house.

Further objects will appear as the description proceeds.

Referring to drawings Figure 1 represents in front elevation one embodiment of the present invention applied to the scantling of a house;

Figure y2 is a view in side elevation illustrating a modified embodiment of the present invention applied to the scantling of a house;

Fi re 3 is a sectional view taken along the line 3 3 ofFigure 1 Fi re 4 is a sectional thefi ne 4 4 of Figure 1.

The present invention contemplates the use of relatively stiff board having lath means attached thereto. Said board may be chosen from a great variety of materials including composition or paper, or may be view taken along minimum of skill in applying to the scant` strawboard, and for certain constructions corrugated board will be preferred. Said board and the lath means willv preferably be covered with weather-proofing material and will be attached to the scantling of a house. The material will be supplied in dimensions for convenient handling and is readily adaptable to attachment by staples or other holding means. The lath means referred to will provide means for holding plaster, stucco, or other wall covering material. One or more layers of board may be supplied, depending upon the choice of the user.

The upright scantlings of a house are indicated by the numerals 1 1. Referringto Figures 3 and 4, it will be apparent that the illustrated embodiments of the present invention show two thickness of corrudated board.l Referring to said figures, it will be noted that on the side of the scantling marked Outside two corrugated members 3 3 are provided, having the three facing sheets 4-4. On the side of the scantling marked lnside, however, only two facing sheets 4 4 are provided. The member 3 distant from the scantlings may have one of the facing sheets 4 4 omitted for the purpose of presenting a corrugated surface to the plaster in a manner which will be referred to hereinafter. Refer-ring to the layers of corrugated material illustrated in Figures 3 and 4, on the side of the scantlin marked Outside, it will be noted that said layers are provided with a layer of lath mea-ns 5. Said lath means may take any of a great variety of forms, being illustrated as comprising relatively heavy furring wires 6 6 and cross wires 7 7 which may be welded or otherwise united to said fui-ring wires 6 6. The lath means 5 may be attached to the layers of corrugated board by means of stitches 8 8, best illustrated in Figures 1 and 3. Strips 9 of relatively thin, tough material, such as'cloth, may be provided on the side of the layers of corrugated board opposite to the lath means 5 for the purpose of preventing said stitches 8 8 from pulling through. Said strips 9 also increase the stiffness of the board.-

The composite sheets of stiff board and the side boundaries orf one of said sheets arev l .45 funring.

. indicated by the numerals 1O-i--10 in Figvided along the top or bottom boundary as indicated by the numerals 11-11. By this construction, continuity of the holding means for the plastic material is provided. The fabricated building material comprising the layers of board and the lath means 5 1s attached to the scantlin by means of staples 12-12. Stucco or ot er plastic maf terial, indicated lby the numeral 13, may be applied to the outside and will firmly grilp the lath means 5. f

eferring now rto the vembodiment' rnf the present inventiony which is illustrated in connection with the inside ofthe ho-use, it

will be noted thatthe board, minus one of the flat facing sheets 4, is faced with'wire lath means 14, which. may 4 be of the 'form generally spoken ofI agchckemrwrg or of any other Ypreferred form. Said vlath means 14 will be fastened to the layers of corrugated board'by means of stitches 15- 15, the fabricated building material being fastened to the scantling lby means of the staples 12-.12 Plaster 16 Amay be applied to the insideof thejhouseand williirmly grip the lmeans l4.-"-.The that the layer of corrugated board adjacent to said lath means is not faced with a flat sheet but with a corrugated sheet will permit the firm engagement of said plaster with' the lath means 14 without the provision of any added furrin pieces. For-the reason stated, the construction illustrated for the interior of the house may `heinferred to as lselfjlt. be clear thatrthe embodiment of the present invention illustrated in connection with-'the inside ofthe Yhoruse may be used on the outside as well, if referred, and that the embodiment illustra d in connect1on with the outside of the house will be equally applicable to both interior and eX,-

terior Work. The building materialaocording'to the present invention will be weatherproof, whereby to prevent ingress of rain or f snow. The corrugated board will prov1de airl spaces whereby the building inaterial according tozthe;v present 'invention will have very good 'heat andsound insulatmg properties. The structure ischeap to manufacture and is very leasily handled, and persons with only a minimum of skill will ave no diiculty in mounting same in a secure manner upon the scantling of a house. Furthermore, the lath means may oe of metal and will have valuable jfunctions in reinforcing the plastic material ap lied thereto. The relatively stiff board will ensure lane surfaces and will protect against the oss of plastic material which is so common in present practice.

Itmay be stated .that the term or relatively stiff as applied to the board used inthe practice of the present invention is to be construed to refer to such stiffness as will result in a substantially flat surface when said board is applied to scantlinigs spaced apart-the ldistances commonly found in practice, which distances ma be said to range from 12 to .24 inches. t will be noted from an inspection of the drawings that the corrugations of the backing member are arranged preferably at right angles tothe upright scantlings 1 1, that is to say, the corrugations are arranged ser horizontally, whereby circulation of air -in a vertical direction through said corrugations is revented. It will be noted also that the building material is substantially imperforate, the holes necessary for the stitches 8- 8 vand staples 12-12 being lfilled up by said stitches or staples.

In the claims forming part of this specification, the term furring means is intended to be broadly construed to cover the furringwires 6; or the corrugated board 3, minus one of its facing sheets 4, which is illustrated in connection with the lath means 14 for interior construction, or other equiva.-

lent constructions which may be preferred.

The described embodiments have been chosen merely for the purpose of illustration. Many modifications -will occur to those skilled in the art. It is intended in this patent to cover all such modifications that fall within the scope of the invention4 4 as defined by the appendedclaims.
